Results for Trunnions, Description : TRUNNION - 1

Trunnion Lifting Load [Tlf]: = ((Fa^2 + Ft^2)^1/2) = ((1169.00 ^2 + 2025.00 ^2)^1/2) * 2.00 = 4676.40 Kgf

Z = pi * (TOD^4 - TID^4) / (32.0 * TOD) = 3.14 * ( 219.10 ^4 - 193.70 ^4) / (32.0 * 219.10 ) = 401810.62 mm.^3

Trunnion Bending Moment [Tmom]: = (TL - 0.5 * TT)/9.807* Tlf = ( 150.00 - 0.5 * 25.00 )/9.807 * 4676.40 = 643.02 Kg-m.

Trunnion Calculated Bending Stress [SBC]: = TMOM * 9.807/ Z = 643.02 *9.807/ 401810.62

= 15.69 N./mm^ [Passed] SBC < Min(0.66* SY* Occfac, .75* SY) (155.07)

Trunnion Cross Section Area [Txsa]: = pi / 4 * (TOD² - TID²) = 3.14 /4 * ( 219.10² - 193.70²) = 82.35 cm^2

Trunnion Calculated Shear Stress [SSC]: = Tlf / Txsa = 4676.40 / 82.35 = 5.57 N./mm^ [Passed] SSC < 0.4 * SY * Occfac (93.98)

Trunnion Unity Check [UCHK]: = SBC / SBA + SSC / SSA = 15.69 / 155.07 + 5.57 / 93.98 = 0.16 [Passed] UCHK, Must be less than 1.

Trunnion Bearing Contact Area [Tbca]: = TOD * TT = 219.10 * 25.00 = 54.78 cm^2

Trunnion Bearing Stress [SBEC]: = Tlf / Tbca = 4676.40 / 54.78 = 8.37 N./mm^ [Passed] SBEC < Min(0.75* SY* Occfac, 0.9* SY) (176.22)
